Financial Atoms and Molecules
Yik Wen Goo,Tong Wei Lian,Wei Guang Ong,Wen Ting Choi,Siew-Ann Cheong
Quantitative Finance , 2009,
Abstract: Atoms and molecules are important conceptual entities we invented to understand the physical world around us. The key to their usefulness lies in the organization of nuclear and electronic degrees of freedom into a single dynamical variable whose time evolution we can better imagine. The use of such effective variables in place of the true microscopic variables is possible because of the separation between nuclear/electronic and atomic/molecular time scales. Where separation of time scales occurs, identification of analogous objects in financial markets can help advance our understanding of their dynamics. To detect separated time scales and identify their associated effective degrees of freedom in financial markets, we devised a two-stage statistical clustering scheme to analyze the price movements of stocks in several equity markets. Through this two-time-scale clustering analysis, we discovered a hierarchy of levels of self-organization in real financial markets. We call these statistically robust self-organized dynamical structures financial atoms, financial molecules, and financial supermolecules. In general, the detailed compositions of these dynamical structures cannot be deduced based on raw financial intuition alone, and must be explained in terms of the underlying portfolios, and investment strategies of market players. More interestingly, we find that major market events such as the Chinese Correction and the Subprime Crisis leave many tell-tale signs within the correlational structures of financial molecules.

Moderators of occupational pressure in female health professionals—Individual differences and coping skills  [PDF]
Siew Yim Loh, Kia Fatt Quek
Health (Health) , 2013, DOI: 10.4236/health.2013.510224

Individual differences and coping skills have influential impacts on stress process by influencing the eventual outcomes of the stressors, contributing to either wellbeing, or illness and negative experiences. The aim of this paper is to explore the individual differences and coping strategies of a cohort of women with health professionals’ occupational pressure. This is a cross-sectional survey, informed by the transactional model of stress and coping framework, and carried out on women health professionals (n = 203) from the Kuala Lumpur Hospital. Multiple regressions were conducted to examine the potential moderators of stress. Women Health Professionals reported stress with six out of eight organizational sources of pressure, with relationship being a key stressor. Their individual differences (mean + SD) were characterised by low drive (7.6 + 1.9-8.2 + 2.0), low personal influence (10.8 + 2.0 to 11.7 + 2.3), moderate control (13.4 + 3.4 to 16.3 + 2.4), and high impatience behaviour (19.1 + 3.8 to 20.4 + 3.3). With Coping strategy, the Life-work-balance coping is a significant positive predictor for five out of the nine outcomes of occupational pressure [state of mind (p < 0.001), level of resilience (p = 0.01), level of confidence (p = 0.003), physical symptoms (p = 0.001) and energy level (p < 0.001)]. The findings show relationship as a key stressor, with a less favourable pattern of individual-differences and an over-reliance on lifework balance coping. Female health professionals, stressed at work, have an undesirable profile of individual difference and a coping strategies, suggestive of attempts to balance the demands of their dual work role. The increasing female into the workforce, warrants more research to inform stress management guideline to ameliorate stress amongst those vulnerable workers. Future studies to examine individual differences of these female-dominated professions across health setting are needed to better inform the pressure-at-work issues for the increasing Asian women health professionals.

The Mainland Chinese Managerial Behaviors and Assumptions since the Economic Reform: The Literature Review and Research Proposition  [PDF]
Jose Wong, Siew-Huat Kong
Open Journal of Business and Management (OJBM) , 2014, DOI: 10.4236/ojbm.2014.21005

China is a country that does not stand still. The nation has been on the move since the launch of her reform and opening-up policy in Chinasome 30 years ago. From the infrastructural projects to the look of her people, there is no doubt that great change is taking place. Many entertain the hope that the change this time is for real: China will come out in this process a different country. Some even venture to propose that “China Model” has appeared as a challenge to “Washington Consensus”. What about the world of Chinese managers? What changes of Chinese managerial styles did we find in these years? This study will attempt to answer these questions as it tries to ascertain the key driver of this managerial style—the managerial assumptions of the Chinese managers. This analysis will attempt to sketch a Chinese managerial style and propose a set of assumptions that could be shaping this style. The different sources of influence that have come to shape the Chinese managerial assumptions since China launched her economic reform in 1978 would be of particular interest in this adventure. Accordingly, several propositions of Chinese managerial assumptions will be suggested for future research.

The Development and Validation of a Figural Scientific Creativity Test for Preschool Pupils  [PDF]
Mui Ken Chin, Nyet Moi Siew
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.612139
Abstract: Testing creativity in general has been well researched but little has been reported on the devel-opment of instruments to test scientific creativity among preschool pupils. This study described the development and validation of a Figural Scientific Creativity Test (FSCT) for preschool pupils. The FSCT consisted of six items which were constructed based on Scientific Creativity Structure Model and scored using an adapted Torrence Test of Creative Thinking. The items were developed through three dimensions called the product (scientific knowledge, scientific phenomena and scientific problem), the process (imagination and thinking) and the trait (fluency, originality, elaboration, abstractness of title and resistance to premature closure). All the items were developed and validated through analysis of item response data of 30 six-year-old preschool pupils in Kota Kinabalu district. Item analyses were conducted to check on item discrimination, Cronbach Alpha internal consistency coefficient, item-total correlations, agreement between scorers, construct re-lated validity, content validity, face validity, and acceptability to pupils. All items showed discrim-ination coefficient range from 0.22 to 0.40. The Cronbach Alpha internal consistency coefficient was found to be 0.806. The item-total correlations range was within 0.541 to 0.866. The correlations between scorers varied from 0.780 to 0.933. FSCT was found to have a total of six items on one factor as a result of the exploratory factor analysis. The item analysis suggested that FSCT could be a reliable and valid instrument in assessing scientific creativity of six-year-old preschool pupils in preschool classrooms.
Unravelling the ORFan Puzzle
Naomi Siew,Daniel Fischer
Comparative and Functional Genomics , 2003, DOI: 10.1002/cfg.311
Abstract: ORFans are open reading frames (ORFs) with no detectable sequence similarity to any other sequence in the databases. Each newly sequenced genome contains a significant number of ORFans. Therefore, ORFans entail interesting evolutionary puzzles. However, little can be learned about them using bioinformatics tools, and their study seems to have been underemphasized. Here we present some of the questions that the existence of so many ORFans have raised and review some of the studies aimed at understanding ORFans, their functions and their origins. These works have demonstrated that ORFans are an untapped source of research, requiring further computational and experimental studies.
Hepatitis B virus X protein interacts with β5 subunit of heterotrimeric guanine nucleotide binding protein

Virology Journal , 2005, DOI: 10.1186/1743-422x-2-76
Abstract: HBV particles were produced in culture medium of HepG2 cells transfected with the mammalian expression vector containing the linear HBV genome, as assessed by commercially available ELISA assay. A cDNA library was made from these cells exposed to HBV. From yeast two hybrid screening with HBX as bait, human guanine nucleotide binding protein β subunit 5L (GNβ5) was isolated from the cDNA library constructed in this study as a new HBX-interacting protein. The HBX-GNβ5 interaction was further supported by mammalian two hybrid assay.The use of a cDNA library constructed from HBV-transfected HepG2 cells has resulted in the isolation of new cellular proteins interacting with HBX.Infection by hepatitis B virus (HBV), an enveloped DNA virus of the hepadnaviridae family, has been closely related to development of hepatocellular carcinoma (HCC). The role of this virus in the series of events leading to the onset of HCC has remained elusive [1]. However, it has been suggested that the smallest protein encoded by the HBV genome, HBX, is involved in the development of HCC [2].Several proteins have been demonstrated to interact with the HBX protein through the use of the Yeast Two Hybrid system. These include the C-terminal portion of a novel human proteasome alpha subunit which possesses a protein sequence of close relationship to that of the 28 kD subunits from other organisms; PSMA7, the α-subunit of the 20S proteasome complex; PSMC1, the subunit of the 19S proteasome regulatory cap complex; XAPC7, a highly conserved proteasome subunit belonging to the α-subunit of the 20S proteasome complex. PSMA7, PSMC1 and XAPC7 were demonstrated to interact with the second Kunitz-type domain of the HBX protein [3-6]. Another two proteins, XAP2 (X-associated protein 2) and XIP (HBX-interacting protein) were found to be negative regulators of HBX. Overexpression of XAP2 abolished the transactivating function of HBX while the specific interaction of XIP to the carboxy terminus of HBX in diffe

Abstract: In response to the market needs and demands, the private higher education in Malaysia has undergone extensive changes in the recent years to the extent that it has been regarded as supplementing and complementing the public higher education system. In view of that, higher education in Malaysia has become a business and burgeoning market for earning revenues. As such, quality has always been a concern to be addressed in higher education reforms in Malaysia and inmost countries. The main objectives of this study were to investigate the students’ level of satisfaction in academic quality in their current university and the academic quality characteristics which were important to them. Two Malaysian private universities were selected for study and participants were 768 undergraduate students from the bachelor and pre-tertiary levels from a wide range of disciplines. Student satisfaction in the quality of higher education, in four specific areas namely academic programme, lecturers, academic services and facilities are presented and the academic quality characteristics in each of these areas which were perceived as important to thestudents are also revealed.
